IILLING-BEPLENISHING-LOOM BOBBIK-SEPABATOB.

To all whom it may concern:

Be it known that I, Mnnvm' L. S'rorm, a citizen of the United States, 'residin at Lawrence, in the county of Essex and btate of Massachusetts, have invented an Imrovement in Filling-Replenishin Loom Eobbin-Separators, of which the 0 lowing description, in connection with the accompanying drawings, is a specification, l ke characters on the drawings representing like parts. v D

This invention relates to filling replenishing looms, and more particularlyto means for separating. substantially full and substantially empty-filling carriers or bobbins as the are ejected from'the shuttle.

In I lling replenishing looms it is nowthe common practice to transfer a filling carrier having a supply of fillmg thereon from a hopper to the shuttle and e ect the filling carrier in the shuttle when such filling carrier is substantially exhausted of fill ng. This operation is referred to as replenlshing the filling. In this general type of loom the ejected filling carriers are thrown into a receptacle or container, and then the fillmg on the ejected filling carriers is removed and forms waste. The amount of waste, of course, will depend on the amount of filling remaining on the filling carrier or bobbin when it is ejected from the shuttle, and looms of this character seek to minimize the amount of filling remaining on the filling carriers when ejected fromthe shuttle, without, however, making partial or mis-picks.

' It happens at times that filling replenishment is called by the filling detecting mechanism before the filling on the filling carrier in the shuttle has been depleted to the desired extent, or while the ejected filling carrier or bobbin contains a working supply of filling. In such case, obviously, the amount of waste filling is increased to a most undesirable extent, because the waste filling has already gone through the several processes of its preparation for Weaving into cloth, and in addition to the cost of the material itself, and the time in preparing the filling, a large amount of labor loss is also involved.

An important feature of the present invention, therefore, consists of means for separating the full from the empty bobbins or filling carriers as they are e'ected from the shuttle during the replenis ing operation. The terms full and empty filling Specification of Letters Patent. Application filed December 84, 1918. Serial No. 347,104.

carriers'or bobbins are hereinafter used in a general sense, meaning that a full bobbin or hlling carrier is one on which there remains when it is ejected from the shuttle, a workin supply of fillin and the term empty filing carrier or b0 bin meaning one from which the filling has been withdrawn to a degree of substantial exhaustion. By separating'the full from the empty bobbins or filling carriers as they are ejected from the shuttle, it becomes possible to return the full filling carriers to the hopper for further use in the shuttle, and to use the filling or yarn still remaining on such filling carrier or bobbin. 1

In carrying the general features of the invention into practical effect, two receptacles or compartments which may be either formed in a container or separately organ-' the substantially empty bobbins to pass to their receptacle or compartment, and to direct the substantially full filling carriers or bobbins to the other receptacle or compart ment.

The above features of the invention and other novel elements and combinations of parts will hereinafter be described in connection with the accompanyin drawings which show one good practical form of the invention which, however, is not restricted to the details herein disclosed.

In the drawings:

Figure 1 is a cross section of a filling replenishing loom at the replenishing side thereof, some-of the parts being omitted for clearness of illustration;

Fig. 2 is a sectional detail on an enlarged scale showing by full. lines the action of the invention when a filling carrier or bobbin having a working supply of fillin' therein is discharged from the shuttle, an by dotted lines the action when the filling carriers or bobbins have been substantially exhausted is provided with the cross or breast 2 from which rises the stand 3 for supportin the hopper 4 which may be of any usua t pe, but as herein shown is of the rotary 'c ass of hop ers. The rotary hopper 4 is provided wit means for carrying a supply of filling-carriers 5 which contain a wor mg sup ly of filling and are to be transferre to t e shuttle under the direction of the filling replenishing mechanism.

he rotary hopper 4 is provided with the usual ratchet teeth 6 by which it may be given a step movement after each filling replenishing operation to position a filling carrier for transfer. When in transferring position the filling carrier may rest against the abutment 7 above the passagewa or throat 8, and the ielding finger 9 is a pited to be moved dziwnwardly to permit t c fillin carrier to pass when it is being transferred to the shuttle.

The stand 3 has mounted thereon the stud or shaft 10 on which is supported the transferrer 11 havin the downwardly extendin arm 12 as usua provided at its lower on with the pivotal I connected dog 13, the end 14 of which in apted to be engaged by the hunter 15 carried by the la 16 when the dog is positioned by the filling detecting mechanism, all as usual in this class of looms. p

The construction is such that when the transverse shaft 17 mounted on the loom frame and carryin the finger 18 is rocked contra-clockwise EFig. 1), the dog 13 .throu h the intervenin connections is raise to present its on 14 into position for engagement by the bunter 15 as the lay moves frontwardly to thereby efiect replenishment of filling. It is not deemed necessary to further explain the details of the filling detcctin mechanism or. the. details of the replenis in mechanism and its -.op eration, as these eatures may be as usual 45 in this. class of'looms, and are well understood in the art.

The lay 16 carries the usual shuttle-box 19 at the re lenishi side of the loom, and the shuttlex has t e opening20 through which a filling carrier ejected from the shuttle b the replenishing mechanism may pass. T is construction also may be of usual and well understood character.

Mounted on a suitable support or attached to the loom frame, is the container 21 which may be provided. with a compartment 22 for receivin substantially full filling carriers or bob ins, and a compartment 23 for receivin substantially empty filling carriers or hobbinsas the -are ejected from the shuttle by the operation of the filling replenishing mechanism. The compartments 22 and 23 are herein shown as formed as part of the container 21, but while this isa preferred embodiment of this feature of the invention, the compartments 22 and 23 or receptacles for the full andempty bobbtllelg may be otherwise formed and associ- &

- The present invention contemplates the provision of means which will permit the emptyfilling carriers to pass to one of the receptacles or containers, and will direct the substantially full filling carriers or bobbins into the ot er compartment or receptacle, to thereby separate the two classes of filling carriers, so that those which contains.

. workin suppl of filling when discharged tainer 21 has pivoted thereto at 24 an arm 25 to which is connected the chute 26, and a p spring 27 acts upon the arm 25 to normally hold the chute 26 in position for receiving the ejected filling carriers into its upper end portion. In' order to conveniently determine the position of the chute 26, a lug 28 on the arm 25 engages a portion of the con- ;aine; 21 which acts as a stop as indicated in e chute 26 may be variously formed and may be connected to. the container 21 by the means shown and described, or by other means, andis provided with an entrance portion 29 which, is received into an o enin 30 formed in the lay below the re-' p enishmg-shuttle-box when the lay is in' substantially its front position, the construction being such that at such times the upper end portion of the'chute 26 and-the lay and shuttle-box "assume the relative positions indicated by Fig. 2. A

Mounted in the chute 26 is the means for separating the -full from the empty bobbins and directing them 'in'difierent paths. In the present instance, the chute 26. is provided with the lugs 31 to which ispivotally mounted at 32 the plate 33, which for identification may be known as the deflector. The plate 33 extends longitudinally of the shuttlebox a substantial distance when the parts are in cooperating relation as indicatedin Figs. 2 and 3, and a s ring 34 normally acts to hold the plate 33 1n dotted line position as indicated in Fig. 2. The upper end portion of the deflector 33 is turned or bent rearwardly as indicated in Figs. 2 and 3, at 35-, for a. purpose that will presently appear. Mounted on the upper porend portion at one end of the entrance to.

the chute, terminates short of the end wall 37 of the chute to provide sufficient space or clearance for the passage of the head or butt ends of filling carriers or bobbins as they pass from the shuttle-box during the replenishment of filling. The guide or abutment 36 has beveled or inclined upper and lower surfaces, as indicated in Figs. 2 and 3, and is adjustably connected to the upper portion of the chute 26. The adjusting means, in the present instance, consists of the threaded bolts 38 and their coiiperating nuts 39, the construction being -such that the space between the guide or abutment 36 and the upper end portion of the deflector 33, when the latter is in its normal or dotted line position (Fig. 2) may be adjusted to suit conditions of use.

When the parts are in normal position as indicated by dotted lines (Fig. 2), and a filling carrier from which the filling has been substantially exhausted is ejected from the shuttle during the replenishing operation, it will pass downwardly between the abutment 36 and the upper inclined end portion 35 of the deflector, as indicated at a (Fig. 3), without tilting or operating the deflector, and will pass downwardly into the receptacle or compartment 23, as indicated at b. When, however, the filling carrier that is ejected froni-the shuttle has a working su ply of filling thereon, as indicated at c ig.-2) it will engage'the upper rearwardly turned end of the deflector '33 as it is forced downwardly by the transferrer 11, and swing the deflectorfrom its dotted to its full line position (Fig. 2), thereby inclining. the deflector into a posi tion to direct the filling carrier and its working supply of filling mto the compartment or receptacle 22, such movement of the. deflector being accomplished against the tension of the spring 34.

In order that the deflector 33 may not instantly return to its normal inoperative position, as indicated by dotted lines (Fig. 3) as soon as the filling carrier has passed the pivotal point 32 of the deflector, the latter is provided with holdin means .for temporarily holding the de ectorin its operative position to deflect the filling carrier with the working supply of filling thereon into its proper compartment or receptacle. The holding means may be variously contrived and be tripped by the filling carrier itself as it passes to its intended receptacle or compartment. In the present instance of the invention, the-lower end portion of the deflector 33 has pivotally connected thereto at 40 an arm 41 which extends rearwardly from the pivot 40 and is constituted as a weight, as indicated in Figs. 2 and 3, the construction being such that when the parts are in normal inoperative position, as

indicated by full lines (Fig. 1) and dotted lines (Fig. 2), the spring 34 holds the lower end of the deflector, and. perforce the arm or weight 41 in the position indicated by full lines (Fig. 1) and dotted lines (F 2) When, however, a filling carrier having a working supply of filling thereon is ejected from the shuttle, and the upper end 35 of the deflector is moved from its dotted to its full line position (Fig. 2) and the lower end thrown outward, as indicated in the drawings, the arm 41 being constituted as a Wei ht, will assume the position indicated by ull lines (Fig. 2), and act on the lower end of the deflector to hold it temporarily in its operative position, at which time it will direct the filling carrier into itsselected receptacle or compartment. When the arm or weight 41 is in the above described position, it should be stopped in such position that the sprin 34 may return the deflector and weighted arm 41 to their normal inoperative position after the "full bobbin has passed. To this end the arm 41 may be provided with a pin 42 which rides in an inclined slot 43 formed in the wall of the,

In order that the spring 34 may assert itself to return the deflector to its inoperative or dotted line position. (Fig. 2) after the full filling directed into its desired receptacle or compartment, the arm 41 has connected thereto a trip 44 which extends into the path of the substantially full filling carrier as it passes toward its receptacle or compartment.

The trip 44 is constituted as a plate pivotally mounted on the lower end of the deflector 33 and appropriately secured to or formed as part of the arm 41, the construccarrier or bobbin has been tion being such that the arm 41 and the trip 44 act in unison.

When a filling carrier contains a substan tially exhausted conditio of fill thereon when .it is ejected from e shutt e, it will pass downwardly into the chute 26, as indicated at a, b (F1 2), and into its intended receptacle 23, whilethe deflector 33 remains in its normal inoperative position, as indicated by dotted lines in Fi 2. When, however, a filling carrier whic still contains a working supply of filling the shuttle by the replenishing mechanism, it will, inspassing downwardly between the is ejected from abutment 36 and the top portion of the deflector 38, force the top portionof the deflector 35 backwardly, and perforce, move the deflector into operative position, -(full lines Fig. 2), where it will be temporarily held by the arm 41, as' hereinbefore described, and as the fillin carrier containing a working supply of lin passes downwardly toward its receptac e or compartment, it will engage the trip or plate 44 and tilt the permit t e spring 34 to return the parts to their normal inoperative position. The chute 26 may have a division wall 45 which may divide the chute into passageways for directing the full and empty bobbins into their appropriate receptacles or compart ments.

By mounting the deflector in the yielding chute 26, provision is made for yielding frontward movement of the chute 26 and deflector to accord with' the position of the lay, but this construction, of course, while preferable, is not necessary to the proper operation of the invention, and the deflector may be otherwise mounted, the essential in this respect beingthat it shall serve to sep arate the full from the empty fillin carriers or bobbins as they are ejected om the shuttle.
